Anderson Cooper claims he never went back to Clinton Global Initiative after solo 2007 appearance, but it appears he went in 2008

Anderson Cooper claims moderating a panel in 2007 was his only connection to The Clinton Global initiative.

Cooper denied:

ANDERSON COOPER: Nearly ten years ago, in 2007 I was asked to moderate a panel discussion at Clinton Global Initiative. Honestly, I can't even remember what the panel was. There were no Clintons on the panel. I think it was on, like, international development aid or, honestly, I have no memory of what it was.

Cooper added, “I wasn't paid. I've never been back to the Clinton Global Initiative. I've never a member of CGI. I’ve never been to a cocktail party for CGI.”

Here is a short video of his 2007 visit.

Is Cooper telling the truth? This blog post after the 2008 CGI claims Anderson Cooper was there too.

Anderson Cooper of CNN was perhaps the most charming of our special speakers.  We had some time together before the speeches started and Anderson had lots of questions about our program. During his speech, he joked about asking me how the PUR sachets worked and that he couldn’t understand anything that I said, but he nodded his head and pretended that he understood me like any good journalist.  I guess that says something about my communication skills!
He spoke movingly about seeing first-hand the impact of unsafe drinking water in Burundi and how he witnessed a child dying from the dehydration caused by severe diarrhea.   Part of our CSDW commitment this year (Download 2008_csdw_commitment.doc) is an awareness raising effort with CNN, Scholastic, and the Do’it’s show on PBS.

You should read the whole blog post to see this was an event at the 2008 CGI. It claims Anderson Cooper was a special speaker at a Children’s Safe Drinking Water (CSDW) event that is described as "a celebration event at CGI called “Promises Made, Promises Kept.”"

Update: According to the P&G Children's Safe Drinking Water blog post, Bill Clinton spoke at the same CSDW event as Cooper. This doesn't make Cooper's claim he never went back after 2007 very believable.
